Benefits of technology

[0013]An object of the present disclosure is to provide an apparatus for damping of a flywheel that effectively attenuates torsional vibration of an engine while preventing the entire length of a transmission from increasing by adding a mass to a dual mass flywheel structure.

Problems solved by technology

In general, there is always imbalance of a driving force due to a change in gas pressure by a piston in internal combustion engines.
A torsional vibration force is generated by such an imbalance in the engines.
However, for such engines, aspects of NVH such as rattling and booming may be deteriorated with increased torsional vibration of the engines, and particularly, an increase of torsional vibration of the pairs of gears in a transmission may cause shock and noise to increase.
Because the available space to mount a damping apparatus to a transmission is limited, the entire length of the transmission increases when a damping apparatus is mounted.
As related art, Korean Patent Publication No. 10-2002-0043925 entitled “Triple Mass Vibration Damping Flywheel for Vehicles” has been disclosed, but it has a problem improving torsional vibration generated in a power train with two or three cylinders.

Abstract

An apparatus for damping of a flywheel, which is configured so that a second mass may rotate in a direction for offsetting torsional vibration of an engine transmitted to a first mass through a damping spring. The apparatus includes: guides disposed between damping springs and guiding the damping springs extending / contracting in a rotational direction by a damping operation; and a third mass arranged coaxially with the second mass, with one end connected to the guide, and relatively rotating in a direction for offsetting torsional vibration of the engine transmitted to the second mass.
